Snyder Industries 300 Gallon Plastic Horizontal Leg Tank

Who hauls a 68 inch leg tank, and what the job looks like

The duty is portable liquid on somebody's deck. A custom applicator carries 300 gallons of blend on a flatbed to keep a spreader running at the far end of a field. A grain farm sets one on a skid behind the shop to hold fuel additive or a herbicide mix. A municipal crew bolts one to a one ton for hydrant flushing and dust control. A landscaper runs one on a trailer as a water tank for a mixer. A shop keeps one on a pallet under the drip of a tote as a transfer vessel. In every one of those jobs the tank is bought by its footprint and its weight rather than by its gallons, because the deck it has to live on is already spoken for. Sixty-eight inches of length is what a short flatbed, a six foot skid or a small utility trailer has to give, and at 38 inches wide it sits inside a standard pickup bed width with room for a strap on each side. The legs are what make it stable there, and they are also the part people get wrong: a horizontal leg tank is designed to bear along the full length of its legs on a flat, continuous surface, which means a deck, a plywood-topped skid or a poured pad, never a pair of joists with a gap under the middle and never a bed with a toolbox in the way of one leg. Strap it over the body at both ends, snug against a bulkhead, and understand what is above the legs: 2,502 pounds of water, 4,754 pounds at the rating, and a load that shifts every time the vehicle turns or stops. Run 300 gallons against your real draw and refill interval in the tank sizing calculator before you settle on the size, and take the freeboard a warm liquid needs from the tank sizing guide. Where the load is a blended fertilizer that has to go out on spec, read the fertilizer-blend tank stratification article first, because a shallow horizontal body layers differently from an upright one and the spreader is where that shows up.

Two 68 inch shells, two 72 inch shells, and the 230 below them

The reason to buy this one rather than a 72 inch molding is four inches of deck and 24 pounds. On a short bed those four inches decide whether the strap lands on the rail or on the tailgate, and 67 pounds against 91 is the difference between setting the tank by hand and hiring a machine for an afternoon. Against SII-1321000N45 there is nothing to choose on the sheet: the two are listed at the same 68 by 38 by 44 inches, the same 67 pounds, the same 300 gallons, the same 1.25 inch outlet and the same 10 inch lid, so the honest answer is that the sheet gives them as identical and we print what it says. Where a fleet already runs one of them, buy the part number that matches, so a saddle, a strap set or a spare lid fits without a second trip. The 230 gallon SII-1280000N45 is the one to take when the deck is genuinely 52 inches and the 68 inch body will not sit flat, and it is listed a pound heavier than this tank while holding seventy fewer gallons. The 335 gallon SII-1004100N45 goes the other way: 56 inches long but 44 wide and 49 tall, gallons bought with width and height instead of length.

The suction path: a 1.25 inch outlet at the low end

• The pump and the drain path: the sheet lists a 1.25 inch outlet, and on a body 44 inches tall there is very little standing height above it, so the pump goes below the outlet and as close to it as the mounting allows. Fall the hose toward the pump, keep the run short, and take the first turn well away from the fitting. A transfer pump set above the outlet on a horizontal tank loses prime at the tail of every load and sounds like a failing pump when it is only a bad layout.
• Prime and protection: a self priming pump or a foot valve is the honest answer on a shallow body, because the last inches of a 68 inch tank cover a lot of floor and the level falls out from under a suction hose quickly. Put a cleanable strainer where a hand can reach it and a run-dry stop on the pump.
• Gravity draw: at 44 inches the outlet sits high enough to feed a mix cone, a nurse hose or a bucket by gravity when the pump is off, which is the quiet argument for a leg tank over a flat-bottom one. Fit a shutoff at the outlet and a second valve downstream so a hose can be changed without draining the tank.
• Access: a 10 inch lid, reached from the ground at this height. Keep it closed while the vehicle is moving and keep its vent path clear, because a lid that cannot breathe while a pump draws will pull a polyethylene wall inwards.
• Service limit: 120 F / 48 C, which is the only limit this sheet publishes.

Break the first joint at the outlet with a flexible connector. A rigid line clamped to a deck and threaded straight into the fitting takes every bump in the road and every pump start into the tank wall, and a leg tank on a moving vehicle sees more of both than a tank on a pad ever will. Carry the valve on its own bracket off the deck rather than hanging it on the tank. Where the load is anything other than water, name the liquid when you order so the outlet fitting, gasket and bolting are matched to it, and where the site keeps a drum or a tank of regulated product on a vehicle, the Snyder Captor SPCC 40 CFR 112 walkthrough is where containment gets argued properly instead of assumed.

Deck work, field work and yard work

This size goes out for custom application and nurse duty on farms, water for dust control and compaction on construction jobs, hydrant flushing at a small utility, wash water on an equipment yard, and transfer service in a shop under a tote. The regulatory question on a farm vehicle is what the load is and who is moving it, and the 49 CFR 173.5 agricultural exemption article sets out the scope honestly rather than promising it covers your trip. For the wider family of applicator and leg tanks and where a horizontal body fits against a loaf or an upright, the applicator and leg tank guide is the comparison to read before ordering.

Chowchilla to the yard at 67 pounds

The SII-1321000C26 is molded at Chowchilla, California. The sheet gives the freight class as LTL under NMFC 156600-02, and it shipments at 68 by 38 by 44 inches, which rides on a pallet rather than as a parcel. The freight cost estimator prices the lane to your ZIP, and the listed price is before freight. At 67 pounds it comes off the truck by hand with two people or off with a forklift under the legs, never dragged by the outlet fitting and never lifted by the lid. Set it on the deck or skid it will live on before you plumb it, then fill it with clean water on level ground and watch the legs, the outlet and the lid seal through a full load before the real liquid goes in. Chalk the date of that first fill on the end of the tank, because it is the only inspection anybody will remember. Put the tank's part number on the maintenance log the day it lands; five years on, nobody remembers which shell it is.
